Figure 2. The topology and comparison with the homologues
of DspB. (a) Schematic topogram generated by the program TOPS
located at the URL (http://www.tops.leeds.ac.uk/). a-Helices are
represented by cylinders and b-strands by arrows. (b) Ribbon
diagram for the refined structure of DspB showing the TIM barrel
down the barrel axis. (c) A 2F[o] -F[c] difference density map
around the putative active site. The map is contoured at 1.5s.
The refined model of DspB has been superimposed. (d)
Superposition of 1HP5 (green) and DspB (magenta) by
least-squares fit as derived from the program SPDBV
(http://www.expasy.org/spdbv/).
